Google CSE Does Not Auto Renew

We use Google’s CSE (Custom Search Engine) for our website and blog. Today I used the search feature and found ads on our site! That did not make me happy. It turns out that Google does not auto-renew your subscription for CSEs, you have to pay manually. They say that they will notify you a month before the subscription expires, but they did not do that. I looked through all emails including spam folders and found nothing. I guess Google think they’ll make more money off of ads than they will my $100 yearly subscription to an ad-free CSE? I marked my calendar next year to remind me to renew the subscription. If you have a CSE, you should too.
